Abstract

La présente invention concerne un nouveau processus pour améliorer la déshydratation lors de la fabrication d'un film comprenant des quantités élevées de cellulose microfibrillée (MFC) sans affecter négativement les propriétés du film. Selon la présente invention, une quantité élevée de nanoparticules est utilisée en tant qu'additif, facultativement avec un polymère.
